Which entity stores validator metadata and governs subnet creation, registration, and validator assignments?

• A. The EVM
• B. The P-Chain
• C. The C-Chain
• D. The X-Chain

Answer: (B)

The Platform Chain stores validator metadata and governs subnet creation, registration, and validator assignments. It handles the network’s governance and stake-related infrastructure, maintaining the validator registry, tracking who is staking, and deciding which validators participate in which subnets. Subnets—custom networks with their own rules—are created, registered, and have their validators assigned through the Platform Chain. The other chains serve different roles: the C-Chain runs the EVM-compatible smart contracts, and the X-Chain focuses on asset transfers. So, the Platform Chain is the system responsible for validator data and subnet governance.
